Quality VS Quantity - Which Do You Choose

I've always heard of clients where their old host suffers from frequent downtimes or their site is always slow, etc kind of problems.

One of the main reason is that lots of people are keen to sign up with host who offers massive amount of disk space and bandwidth at very low prices.

This is actually called "Overselling", as the host will try to limit cpu and ram resource usage. This is normally only written in their Terms Of Service (TOS).

As such, I would like to conduct a poll on "Quality VS Quantity - Which do you choose?" to understand the mentality of consumers today.
